depends on your laneing partner whether you go jungle. i hate fail ww that go jungle even if thier lane partner is a complete noob and feeds like a mofo kos he cant 1v2.
when you play ww u need to make sure ur lane partner is competent and can not only survive. (hate noobs that just let tower die) but also stop other team takeing tower. it is essential that as jung ww you realise when the laneing phase is over. it is better if your team initiates ganking phase first as you will most likely be able to get ahead into pushing phase if u can do a good team gank
